SPECIFICATION forming part of Letters Patent No. 604,585, dated May 24,1898.

Application filed May 12, 1897- Serial No. 636,148. (No model.)

To 00% whom it may concern:

Be it known that 1, JOHN S. JARDINE, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Stair-Carpet Fasteners,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a stair-carpet fastener formed of a body havingspurs or points on the ends thereof adapted to be located in front ofthe riser of stairs and have said points enter the tread and the nosingthereof, thus firmly holding the carpet in position and nicelystretching the same, said body consistin g of a bar formed of sectionslongitudinally movable and adjustable on each other, a rod which ispivoted on one of said sections, the outer end of said rod and theopposite end of said bar having said spurs or points thereon, and meanson said bar and rod for adjusting the sections of the bar, said rod andmeans being concealed by said bar.

It also consists of details of construction, as will be hereinafter setforth.

Figure 1 represents a front view of a staircarpet fastener embodying myinvention. Fig. 2 represents a vertical section thereof. Fig. 3represents a rear view thereof on an enlarged scale; and Fig. 4represents a longitudinal section on line x m, Fig. 3.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a stair-carpet fastenerconsisting of the channeled bar B and the .pivotal rod 0, formingtogether a toggle, said bar being channeled in its longitudinaldirection and receiving said rod in the back thereof. The upper end ofsaid rod 0 is pointed, as is also the lower end of the bar B, formingspurs on said parts, it being seen that in applying the fastener thespur of the rod is presented to the under side of the nosing D, and thatof the bar Bis presented to the tread E, as shown in Fig. 2. Then theupper part of the bar is pushed toward the riser, whereby the spurspenetrate the carpet and wood, and the upper portion of the bar closesover the rod with somewhat of a snap, thus retaining the spurs in thewood, preventing the bar from moving outwardly, and releasing thefastener, the carpet being also nicely stretched. It will be noticedalso that the rod is received within the adjacent portion of thechanneled bar and thus concealed, while said bar presents the generalappearance of a continuous or unbroken surface in front.

The fastener is adjustable to risers of different heights, for whichpurpose the bar is formed of sections F and G, which are fitted to slideor move on each otherin longitudinal direction, and the rod Oispivotally connected with the section F intermediate of the ends of thelatter, the pivot of said rod carrying the dogs or pawls H, which areadapted to engage with the ratchets J on the section G, it being evidentthat when the dogs are thrown out from the ratchets the sections may bemoved one on the other, thus shortening or lengthening the bar, as thecase may be, according to the requirements. When the adjustment to thebar is accomplished, the dogs are engaged with the ratchets, whereby thesections are interlocked and the two-part bar is coupled as one andpresents in general respects the appearance of a single surface,

concealing the rod, the dogs, and ratchets, which, being on the back ofthe bar, are covered by the same.

It is evident that by drawing out the bar the toggle opens and the spursemerge from the wood and carpet, the fastener then being removed fromthe stairs.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. As a new article of manufacture, a staircarpet fastener consisting ofa bar formed of sections longitudinally movable and adjustable on eachother, a rod pointed at its outer end and pivoted at its inner end toone of said sections intermediate of the ends thereof, the outer end ofthe other section being pointed, and means on the back of said bar androd adjustably coupling said sections, said bar inclosing said rod andthe coupling means and concealing the same.

2. A bar formed of sections adj ustably connected, a rod pivoted to onesection of said bar, a dog on the pivotal end of said rod, and

a ratchet on the other section of said bar,

adapted to be engaged by said dog, the outer end of said rod, and theend of the section opposite to said rod having spurs thereon.
